Check Out Nightmare Zone and the First Fifteen Minutes of Sonic Lost World

Hardcore Gamer: Here you can get a very brief introduction to the story and see a few stages. For those retro fans out there, make sure to keep an eye out for all the winks to the past. The second video covers the Nightmare Zone, which is what the Nights DLC is called. This video does cover the whole DLC pack, so don't think there is more to the DLC.
